--- Quote ---Are there any other suitable models out there that I may have overlooked? --- End quote --- Certainly not when it comes to affordable "real" 12bit (i.e. without restrictions). At the moment, the 12-bit is really hyped. In this hype, it's easy to overlook the pitfalls of higher resolution, especially when it has to be cheap. The signal display on the SDS2000X HD, for example, is not comparable with that on the SDS800X HD, although both displays have the same resolution and a smaller display would normally have an advantage, which is not the case here. Also, during the time I had the SDS800X HD in the house, I could not find a clear test situation where it clearly stands out from a low-noise 8-bit scope like the SDS1104X-E in terms of signal presentation. And that is the point. What do you expect from the higher ADC resolution, but what the brochures of all manufacturers always emphasize? A clearer representation of the waveforms. If I have the same display on the screen as on my old 8-bit scope, then the 12 bits are of little use to me. But I experienced this difference with the 2000X HD. |

The last. In the SDS800X HD thread I´ve posted the difference, will search for it tomorrow. |

But what costs much is the X-axis resolution ! <= the bottleneck (cost related) of any scope is the X-axis, not the Y-axis ! :palm: --- End quote --- Thanks for that, I second that but additional to GS/s I think 12Bits are really "nice to have" and nowadays affordable. --- End quote --- hi Markus, you have a Siglent 2104Xplus... me too ! So, I guess that, like me, & thanks to smart guys from the forum, your 2104X+ has beeen converted to a stunning 2504X+ ("stunning" given the price you paid for the 2104X+...) : correct ? If correct (you have a 2504X+), why are you looking for a "cheap" alternative to your 2504X+ ? Back to basic : the price of a scope is related to : BW & sample rate. Only these 2 features... simply because only these 2 matter ! :-+ (1) based on that : a 2104X+ converted in a 2504x+ is still a bargain ! So, given that I have a 2504X+, me too, I was looking for an alternative a few months ago. But, given (1), I looked for a scope that would go far above the feature of my 2504x+ => to get a duo of scope : the 2504x+ to measure basic stuff / the other to measure way above the limits of the 2504x+ What was "far above" at "fair price" ? the GigaWave sampling scope ! but I bought instead an old Picoscope 9211a (same price & more features... I wanted a Pico for a long time because of display/remote/etc), and it's a gem, like the GigaWave (price tag = 3kEur)) Of course, I'm talking about these alternatives because I get stuck @ the lower end of the 2504x+ : 1ns & below If it's not your case, looking for an alternative to your scope is useless If it's your case : get the GigaWave to backup the 2504x+ & go deeper if this post is not ok somewhere, please reply to explain where I'm wrong :-+ |

AFAIK It's the best DSO out there, capable of high BW (with hack) for around €1,250. But I really would like to have a new DSO with stronger and better FFT capabilities and also state of the art GUI and features. Maybe I also should take the Magnova DSO´s into closer consideration? They are higher priced, of course, but look very promising. |
